Mine would be fire breath. I love using it in full dragon plate, just looks cool. Especially since its good on a wide range of enemies and lighting oil traps. The funniest thing is roasting bunnies and chickens!
Has anyone ever used Dragonrend and have the dragon completely ignore it? I mean they are glowing and they were hit, but they fly on as usual.
I enjoy using the Throw Voice shout... Fun to use while sniping!
It's great fun to Fus To Dah at the head of a big table and send plates and salmon steaks flying across the room.
You can also hold a dead bunny over your head, drop it just as you shout, sending the thing flying hundreds of feet. It's possible to punt them over city walls and make it rain dead bunnies in Whiterun.
